IMPROVEMENT IN THRES HING MACHINES AND SBPARATORS.

TO ALL WHOM lT MAY CONCERN:

Be it known that I, H. W. MATTHEWS, of Chicago, in the county of Cook,and State tr Illinois, have invented a new and useful improvedGrain-Threshing Machine and Separator; and I do hereby declare that thefollowing is a full, clear, and exact description of "the constructionand operation of the same, reference being had to the annexed drawings,and letters of reference marked thereon, making a part of thisspecification, in whichp v Figure 1 is an elevation of my improvement inthreshing machine and separator.

Figure 2, a perspective representation of the same, with one side oftheseparating-box broken away to show the conveyor and rakes.

Figure 8 is a plan view of the rack detached from the separating-box.

Figure 4 is a transverse section of my improvement taken through theline at :v, fig. 1. p

The nature of my invention consists in the use of a slotted rack placedlengthwise of the machine and in the rear of the cylinder, and arrangedso as to allow a series of reciprocating rakes to operate in said slotsof racks, and permit the grain and chat? (separated from the straw) topass through between the slots of the rack and fall into a suitableconveyer-trough placed below the rack and rakes, from which place it maybe carried to the riddles for final separation by means of a spiralconveyer operated in said trough. By this general arrangement andconstruction. the cost of producing a complete grain-separator andthresher may be materially reduced, and operated with less power andcost of repairs than the machines now employed for like purpose. And theprocess of separating the grain from the straw may be accomplished atmuch better advantage than when riddles are relied upon for doing theentire work of separation.

p A represents a longitudinal box, in which my separating and conveyingdevices are placed. This box is also arranged so as to support thecommon spiked cylinder '13, feed-table C, and cranh-shaftD, figs. 1 and2, which operate the reciprocating rakes E in the slots Z, figs. 34. GG-G are theslots of the rack, any number .ofwhiclrmay be'used tocorrespond with the width of box A, rakes E, and separating capacityrequired. H, fig. 4, represents the trough placed under rack G G G- forthe purpose of receiving the grain and eh'afi' passing" through saidrack, from which trough it is conveyed by couveyer I, figs. 1 and 4, tothe common riddlesplaced in the usual position at the rear endtof boxA.' v

Operation.

In the drawings my device is represcntedas being operated by means ofband 0, fig. 2, passing over pulley J, attached to the shaft of cylinderB, and around pulley R, which is attached to crank-shaft D, andmade tooperate rear pulley S by means of connecting-rod M. I do not claim anyspecial way of applying the power to the rakes and conveyor, as they maybe run by means of belts passing over pulleys situated at any c0nvenientpart of the machine, or by applying the power directly to the pulley N,attached to the shaft of the conveyer I; the important considerationbeing to give the rakes E a sui-tahlereciprocating motion for separatingthe grain from the straw, and carrying it, by means of conveyer-I, tothe riddles for final separation; of the grain from the chaff. l

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent ofthe United States, is I The combination ofthe rack-G G G, rakes E, and cohveyer I, when construlctedsubstantiallyyas and foi. the purposeset forth. a HUGH W- MATTHEWS.
